I am hearing a clunking noise when shifing fro p to r and n to d

When I shift from park to reverse and neutral to drive, I am getting a clucking noise. This started at approximately 1300 miles. Ford says it is a character of the Mustang. I disagree with Ford and think there is a problem with my Mustang.

Backlash in the driveline, but not necessarily from the axles. The Mustang service manual has a section on "Clunk Diagnosis." You should look up your model year's service manual and see what it says (sorry I don't have one). Honestly I think it's an engineering design problem versus actual wear or a service problem. The ring gear in the axles are supposed to have a super tight level of tolerance, but in reality they don't and you get excessive play, translating into a clunk when shifting from drive to reverse and vice-versa. Some of the check items listed in the "Clunk Diagnosis" are not very likely with such a low mileage car, items like motor mounts, tranny mounts, u-joints, slip yoke, clutch pack, etc. I'm more inclined to look at the differential - pinion shaft, or loose fit of axle shafts to side gear splines. My suggestion to you is have someone shift the car while you lay beside the car and listen to where the clunk is coming from. My guess would be the rear end/diff - unless you've been beating on the clutch pack lol.

A minor clunk is fairly normal. If it is major you may have a problem.
Take it to another dealer and get their take on it and document all
your complaints and visits to Ford in case you have to make a claim
on the warranty. Some service managers will be glad to talk to you
on the phone and you may get some good information that way.

Yes this is the same noise my Mustang also making, i gave
it for servicing and they said they changed the some part
but after that its coming again and they said we need to
keep the car and have figure out.
Not happy with Ford

Having the same problem with mine, ford tried to
tell me it was a lubrication issue. I call bs!! I haven't
had the car a year and only around 10,000 miles.
Also the engine dies while driving down the
highway, and they just replaced the throttle body.
Not happy with this car at all. This is the 4th time it's
been in the shop since I've had it.

I have the same issue with my 2017 Mustang GT, just a couple of weeks old. It mainly happens when engaging Reverse from Drive or Park. It is Not very loud but can definitely hear it with the door open. Took it t 2 dealers, the Supervisors, tranny specialist checked it and said it was absolutely normal and that it is just the engagement in the opposite direction and when the slack is taken up, the noise is from that engagement. Is it really normal??

I just got my 2017 mustang gt about a month ago, i have driven
it and has about 2,856 miles on it and have the same problem. i
took it to the dealer and they have the car for a day and they
come up nothing. They said they tried two of the mustangs they
got same year and model and they got the same reaction so they
contact the factory and ford said its the design and its normal on
all of them so i guess it's a ok!! so far nothing's wrong with it and i
like it...

I have a 2016 convertible. Clunking started at 4,500 miles. After
over a month in dealer's shop and about $3,000 in warranty repair,
dealer and Ford tell me sound is normal and characteristic of
Mustang. Trying lemon law. Ford will not admit there is a problem
and are fighting it all the way. You tube has videos of same problem.
Local car repair and transmission shop tell me this is a problem and
is not normal. Very frustrating to fight Ford on this.
